LIKELY — Residents of a remote British Columbia community who have been surviving on donations of bottled water since a tailings dam failed and released mine waste into a nearby lake are no longer under a water ban, health officials announced Friday as they partially lifted restrictions on drinking, bathing and swimming.

As many as 300 people were affected by the water ban, which took effect on Monday when 10 million cubic metres of water and 4.5 million cubic metres of silt were released from the tailings pond at Imperial Metals' Mount Polley gold and copper mine, about 600 kilometres northeast of Vancouver.

Dr. Trevor Corneil of Interior Health said the town of Likely, B.C., which is the closest town to the mine, and points north on the Quesnel River can use their water as they normally would. However, the ban remained in effect for residents and tourists along southern parts of the river and Quesnel Lake, along with Polley Lake and Hazeltine Creek, which are adjacent to the mine.

The water ban was partially rescinded as the provincial Environment Ministry released a second round of test results that showed water in the area was within guidelines for human consumption.

"We do feel comfortable in the context of risk for human health rescinding the order (in those areas)," said Corneil. "It meets the Canadian drinking water standards, as well as standards for potable drinking water in multiple systems."

The Cariboo Regional District said 100 to 200 residents were still under a ban, though the precise number is difficult to count because so many tourists come and go from the area.

The second round of results were based on samples taken on Tuesday at various spots along Quesnel River.

"Analysis of these samples indicate that none of the chemical and physical parameter concentrations exceeded B.C. or Health Canada drinking water guidelines," said a memo that was distributed with the results.

All five testing sites had zinc levels above chronic, or long-term, exposure limits for aquatic life, which an accompanying memo said could be a problem if it persists.

"Further samples will be collected to identify whether this concentration remains at this level over a longer period, which would indicate a greater potential impact to the most sensitive aquatic life," the memo said.

One of the reasons health officials are reluctant to lift the water ban entirely is Polley Lake —which flows into a creek that drains into Quesnel Lake — is currently plugged by tailings debris. The lake's water level is much higher than normal and officials are worried the debris could break apart and send a dangerous wave of untested water down the creek.

Imperial Metals Corp. (TSX:III) is building a pipe to manually divert the lake's water, but Environment Minister Mary Polak said water from Polley Lake wouldn't be allowed to enter Quesnel Lake until it meets drinking water guidelines.

At a community meeting on Thursday night in Likely, several residents objected to sending more contaminated water into Quesnel Lake.

A provincial government news release said material continued to flow out of the tailings pond Friday, though it had "decreased dramatically."

Imperial Metals is building a temporary berm to prevent water and tailings from leaking out, but it's not expected to be finished for weeks.

"The construction of the berm to prevent further tailings from flowing into Hazeltine Creek began last night (Thursday) and the company estimates that it will take about three weeks to complete," said the news release.

The Environment Ministry sent Imperial Metals a pollution abatement order on Tuesday, and the ministry said the company has so far complied with reporting and planning deadlines.

There have been questions about the stability and maintenance of the tailings pond, though the company insists the dam was properly built and maintained and that there were never any problems with the dam before.

A consultant who authored an environmental report in 2011 said this week that the tailings pond water was too high when he examined it, and a former worker has also come forward to say he warned his superiors that the dam wasn't safe.

Knight Piesold Ltd., an engineering firm that was previously the engineer of record for the tailings facility, issued a statement Friday that said when it ended its relationship with the mine, it sent the company a memo that noted "the embankments and the overall tailings impoundment are getting large and it is extremely important that they be monitored, constructed and operated properly to prevent problems in the future."

Knight Piesold's statement said that when it was involved with the mine, the tailings pond was "operated safely and as it was designed."

The provincial government's written update on Friday said the company submitted yearly dam inspection reports and that the mine had received 16 geotechnical inspections since 1995. Its most recent inspection last September did not result in any inspection orders.

Meanwhile, a group of Tahltan First Nation elders is adding to the opposition of mining projects in British Columbia following the Mount Polley tailings-dam failure calling for a blockade today of the Red Chris mine project near Iskut in the far northwest.

Red Chris, a $500-million copper gold mine under construction, and the Mount Polley mine are both owned by Imperial Metals Corp. and the elders, under the name the Klabona Keepers, issued an advisory calling for the action “in response to the (Mount Polley Mine) disaster and our serious concerns over (Red Chris Mine).

The Klabona Keepers, according to the group’s website, is an organization of elders and families who use the Tahltan’s traditional lands near Iskut known as the “sacred headwaters of the Stikine, Nass and Skeena Rivers.”

The Tahltan First Nation was in the process of negotiating an impact and benefits agreement with Imperial Metals and the government, but on Aug. 6, Tahltan Central Council president Chad Day said the Mount Polley situation “obviously means we have new questions and concerns that we must discuss.”

“To date, no IBA has been signed and the mine does not have all of the permits required to open,” Day said in the statement.
